My TV Display is bad it is too dark in the day I cannot see anything Update (09/03/2018) My TV Display is horrendous it is too dark during the day and does not give me a clear picture

@joyous possibly a bulb, ballast or (less likely) a DLP chip error. We would have to see what you see. Post some images of the display so we can see what you see Adding images to an existing question Besides regular hand tools, you will also have to have a pretty good multimeter to measure the ballast.
